Groupthink is defined as:

• A. A barrier where the desire for group harmony overrides critical decision-making
• B. A process that encourages dissenting opinions
• C. A method to improve independent thinking
• D. A reference to the bystander effect

Answer: (A)

Groupthink is the phenomenon where the desire to maintain group harmony and consensus overrides critical thinking and realistic appraisal of alternatives. In such settings, people may withhold doubts, self-censor, or pressure others to conform, and members or leaders may act to suppress dissenting information or viewpoints. The result is flawed decisions because important risks and alternatives aren’t fully explored, and unethical choices can slip by unchallenged in the name of unity. This matches the chosen description because it centers on harmony suppressing critical decision-making. It isn’t about encouraging dissenting opinions, improving independent thinking, or describing the bystander effect, which is a different concept about how people react in emergencies.
